Mysterious front left suspension noise

[Budz]

Hi there, my 2012 verso- S Automatic car has this suspension noise from the front left when going over humps ( only when the accelerator been pushed).

Ive shown the car to Kwick-fit, National tyres and my friend who's a master technician at a Honda garage to see if they can find the issue but no success. 

My friend thought it was the strut mount so he changed it but the noise still there. He said the wishbone is good so its not the wishbone either. The wired thing is this happens only when giving gas in when going over humps, if no gas given then no noise. 

Has anyone come up with this issue?

Sorry I forgot to say my friend also changed the left drop link along with the top mount.

Where is the roll bar bushes please,  is it on the left suspension?

Bit of an update- took the car to Toyota garage ( so kind of them not to charge  me), went on a test drive with the mechanic so I could make him to listen to it. He said one of his family member has the same car but the  manual and has the same noise but he couldn't look in to it yet.

He put the car on the ramp to find both front lower arms ( wish bones) need replacing and hopefully it will fix the issue. He did show me the rubber bushes on the lower arm which has some cracks.

Toyota said all x4 wheels need aligned as well after the repair and quote me around £1100

I will give this a thought and see if an independent garage can do it for cheaper. Each front lower arm at GSF like £62 and I guess both sides its a 2hr job...

Final update!

My friend's garage changed both front suspension arms. Cost me £86 for both from AutoDoc (£110 saved comparing to the GSF for the very same highend brand). Labour cost me £110. Took just 1hr for both lower arms.

The noise is now gone. 

Sadly I wasted £110 for left top mount and drop link thinking it was the issue, but hey atleast I saved a massive amount still not going with the Toyota fee of £940

Happy days

I was told to get the front wheel alignment done so I will do it with National tyres for £17.50 with the discount coupon next week
